3M 7100098207 Adhesive Back Sanding Sheet 80 Grit

Product Description

The 3M 7100098207 is an adhesive-back sanding sheet roll designed for continuous-feed and hand sanding applications where consistent cut and a secure backing bond are required. The abrasive mineral is ceramic aluminum oxide, a hard-wearing grain that fractures during use to expose fresh cutting edges, making it well suited for aggressive material removal on wood, composite, and metal surfaces. The roll measures 2-3/4 inches wide by 20 yards long and uses a C-weight paper backing, which balances flexibility with tear resistance. The pressure-sensitive adhesive back allows the sheet to mount directly to a backing pad or fixture without additional fasteners. Weight is 1.59 pounds per roll.

This sanding sheet roll fits production-line sanding stations, portable belt-style finishing tools, and custom shop fixtures that accept 2-3/4-inch-wide adhesive-back media. At 80 grit, it is suited for initial stock removal, shaping, and surface leveling before progressing to finer grits. Typical users include finish carpenters, millwork shops, cabinet fabricators, and general contractors performing surface prep on wood trim, cabinetry, or painted steel components.

Key Features

• Ceramic aluminum oxide abrasive grain — self-fracturing for extended cut life
• 80 grit — aggressive stock removal and surface leveling
• C-weight paper backing — flexible yet durable for contoured and flat surfaces
• Pressure-sensitive adhesive back — direct mount to backing pads without added fasteners
• 20-yard roll length — continuous supply reduces changeover frequency in production use
• Blue sheet color for easy grit identification

Compatibility

Designed for use with backing pads and fixtures that accept 2-3/4-inch-wide adhesive-back sanding sheets. Verify pad dimensions and surface material compatibility before use.

Installation Notes

Clean and dry the backing pad surface before applying the adhesive sheet to ensure a firm bond. Press the sheet firmly from one end to the other to eliminate air pockets. When removing a spent sheet, peel at a low angle to minimize adhesive residue on the pad. Wear appropriate eye protection and respiratory protection when sanding materials that generate fine particulate.
